CAR-ILLUMINATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 690,145, dated December 31, 1901.

Application filed June 15,1901. Serial No. 641731. (No model.)

To all whom it may concern: vals to thoroughly illuminate the interior of Be it known that LWILLIAM S. HAMM, a citithe car. zen of the United States, and a resident of The casing 11 of the apparatus consists of Chicago,county of Cook, and State of Illinois, a chambered arch conforming to the contour have invented certain new and useful Imof the deck of the car.

The sides 14 of paratus which is particularly adapted for use the casing are provided with light-emitting in railway-cars, and has for one of its objects apertures which are closed by diaphanous to provide a simple and effective illuminator plates 15, eaclrof which is mounted in a designed to be substituted for the chandelier hinged frame 16, the said frames being held '15 and other hanging or suspended lamps usuwhen closed by spring-catches 17, engaging ally employed and which are objectionable wires 18, secured to the inner face of the sides owing to the space utilized thereby and the 14 of the casing. Access is had through the heat created by the same within the car. medium of these openings for the purpose of A further object is to provide means comigniting and extinguishing the gas at the 20 bined with an illuminating apparatus to efburners 19, each of said burners being profeet thorough ventilation of the car. vided with a cock 20, and gas is led to the The invention comprises, in general terms, burners by a pipe 21, located inthe bottom a longitudinally-chambered arch secured to of the chamber of the arch or casing 11.

50 being provided and located at suitable inter- In addition to spacing the flame-chamber from the car-deck and providing a chamber through which a current of air is constantly passing,

so as to avoid injuring the deck, this construction also secures a proper ventilation of the car, the warm air therein passing through the openings 26 into the ventilating chamber,

thence through the apertures into the flue 24 and to the atmosphere.

For the purpose of ventilating the flamechamber in order to keep it comparatively cool, as well as to supply air to support com bustion, a series of apertures or inductionports 30 are provided in the walls 14, and within the chamber and adjacent to these walls are located tubes 28, each having two series of oppositely-disposed apertures 2929,

the apertures on opposite sides of the pipe 33, the upper end of the fine 22 being laterally apertured and space being left between the cap 32 and the flue 24 and the band 33 to allow the free exit of vapors.

The apparatus provides for wide distribution of the illuminating agents, so that there is avoided any brilliant center of illumination. The light comes from above. Each arch throws light toward both ends of the car, securing effective and pleasing illumination. The apparatus'is simple in construction and compact in form, utilizing much less space than the lamps ordinarily used, and His readily adaptable, with slight modification, to any construction of railway-car. The arrangement is such that the flame-chamber is thoroughly ventilated, thereby making the apparatus especially valuable for burning acetylene gas, and in addition it combines means for effectually ventilating the car.

I If desired, the casing 11 may be ornamented by providing the bottom thereof with jewelclosed apertures 27.

While I have shown the diaphanous plates 15 as elliptical, I do not confine myself thereto, the shape and number of the same being immaterial.

It maybe found desirable to install the illuminating apparatus during the building of the car, it being, in effect, a part of the car construction. It will be obvious that this will be no departure from the spirit of my invention.

This is a matter of considerable I claim as my invention 1. In combination with a railway-car having a deck, a chambered arch crossing the deck and having diaphanous sections in each side face, and an illuminating agent within the chamber of the arch.
